why not anonymous for the whole file?

[reveman, 2013/02/22 01:26:44]

trying to be consistent with ash.

is 2u not enough?

[reveman, 2013/02/22 01:26:44]

Done.

can you stick a comment on/in each of these tests to say what they are testing?

I think this is testing that the native window is shown/hidden when the foreign
window is shown/hidden?

[reveman, 2013/02/22 01:26:44]

Done.
